MTV has confirmed that production of Jersey Shore’s fourth season, set to shoot in Florence, Italy, has been postponed, partly due to a visit from the country’s president, Giorgio Napolitano. The network said in a statement, “Production on Jersey Shore will begin this week, following the Italian presidential visit to Florence. In the ongoing spirit of cooperation, we’re waiting until his official visit concludes to start filming.” EW has learned that the presidential visit would have hindered production in terms of which locations the cast would be able to visit, hence the brief delay.
